Luis Suárez will not be investigated over an alleged stamping incident with a Zenit St Petersburg defender, according to Uefa.

Suárez was pictured stepping on Tomas Hubocan's back near the end of a Europa League match at Anfield last Thursday. Some commentators suggested the Liverpool forward deliberately stamped on his fallen opponent.

Referee Bjorn Kuipers, a Netherlands official on Fifa's shortlist for selection to the 2014 World Cup finals, did not punish Suarez.

Uefa can use video evidence to review incidents. But the European football body said in a statement that its "disciplinary unit has decided not to open a case."

Suárez scored twice from long-range free kicks in Liverpool's 3-1 victory. But Zenit, who won the first leg 2-0, advanced to the last 16 of the tournament on the away-goals rule.
